    Hello @Ole

    It is safe to switch from Courier to Dovecot, user data will not be affected.
    After switching to dovecot mail server will be secured by certificate from "tools and settings > ssl-certificates > certificate for email" in case mail clients using server name as the mail server.

    Hello @Vasil,

    Yes, usually there're no issues when doing such change.

    Moreover, Postfix provides more functionality like SNI and autodiscovery.

    Is it safe to change the IMAP from Courier to Dovecot (and vice versa) if there are already lots of email accounts on the server? I am concerned, if changing the IMAP/POP3 servers deletes any user data (passwords, configs, etc.) as we have lots of domains with emails on the our plesk server.

    And another question: We like to change from Courier to Dovecot as the new Plesk Obsidian now enables us to select individual SSL/TLS-Certificates for IMAP. On the current state we have told our customers to use our server name (i.e. our-server.com) when connecting via IMAP to their customer domains (i.e. customer-domain.com) and selected a certificate for our-server.com in "tools->ssl-certificates->certificate for email". By this they don't get any certificate warnings. So when we change this now, will the server still use this certificate until we chose a different certificate for the custom-domain.com? That would be good to know, or otherwise we would need to inform our customers in advance of this change.

    Thanks George, 

    the switch from Courier to Dovecot mainly worked good, but we still have some issues afterwards:

    * Email folders now have two folders for sent messages: One is named "sent", the other "sent messages". All sent messages prior this change are in "sent messages" and all sent messages after this change are stored in "sent". 

    * The same happened for spam folder: now there are 2 folders: "spam" and "junk"

    * We have difficutlies with special chars in folder names, see https://support.plesk.com/hc/en-us/articles/360010139880?page=1#comment_360000871899

    The rest works good.

    Hello Ole

    Thank you for letting us know.

    Talking, about mail folders, you may try merging them, for example, as described here: https://stackoverflow.com/questions/16476944/merging-two-dovecot-maildirs

    Is it safe to switch to Postfix from Qmail on a Ubuntu server?
